| 中文摘要: |
| 巴氏新小绥螨Neoseiulus barkeri Hughes释放袋悬挂于板栗树主干后，沿植株枝条由近及远，逐渐扩散，在距挂袋处1 m、2 m、3 m和4 m处的叶片上分别于释放后1 d、1 d、3 d和7 d时达到种群密度高峰，7 d最远扩散距离达到距挂袋处4 m以上。距挂袋处不同距离巴氏新小绥螨的密度相差较大，由近及远，密度逐渐递减，相应的，不同距离处板栗小爪螨Oligonychus ununguis 的密度由近及远逐渐增大，1-3 m处板栗小爪螨的密度明显低于对照株，4 m处的板栗小爪螨密度与对照株相近。 |
| 英文摘要: |
| Neoseiulus barkeri gradually dispersed from release point to far along branch of chestnut tree (Castanea mollissima)after releasing, the population density reached peak after 1 d, 1 d, 3 d and 7 d at the distance of 1 m, 2 m, 3 m and 4 m to release point respectively, the farthest dispersal distance was more than 4 m at 7 d The population density of N barkeri gradually decreased from release point to far along branch The population density of Oligonychus ununguis gradually increased from release point to far, the population densities of O ununguis at the distance of 1 m, 2 m and 3 m to release point were lower than the control tree, but it was similar with the control tree at the distance of 4 m |
